What is the difference between an interlaced and non-interlaced mode?
Interlaced is a technology used in a standard television display. The electron gun will draw the odd numbered lines from the top to the bottom of the screen, then will come back to the top and draw in the even numbered lines. Flickering occurs because the non-refreshed lines fade before they are redrawn. In the non-interlaced mode, the screen is drawn from top to bottom, line by line, which produces less flicker and less eye strain for the end-user.
